Actually - thinking about it more (and testing the hypothesis by
attempting a kernel build), I believe what may have happened is that
vnode_if.h somehow gained an extra copy of itself - the file doubled to
47k in length and this problem persisted through multiple make clean;make
depends.  I've tested the effect this has and it's definitely what I was
seeing: kernel compile proceeds most of the way through then dies with a
lot of crap like you'd expect: 

...
vnode_if.h:1090: warning: previous declaration of `vop_strategy_desc'
vnode_if.h:2212: warning: redundant redeclaration of `VOP_STRATEGY' in same scop
e
vnode_if.h:1094: warning: previous declaration of `VOP_STRATEGY'
vnode_if.h:2214: redefinition of `VOP_STRATEGY'
vnode_if.h:1094: `VOP_STRATEGY' previously defined here
vnode_if.h:2223: redefinition of `struct vop_bwrite_args'
...
